Lemon Tree Insect Problem

[kk550]

Hello,

I have a lemon tree and there is some kind of bug that is only attacking the new growth, causing the leaves to wither and become somewhat discolored. Whatever it is, it also leaves a white substance behind. Has anyone here seen this before? I'm trying to figure out what's going on.

Thanks for any help you can provide.

Hard to say without pictures. Post pictures of your tree and close ups of the leaves.

... and also tell us where you are located and what kind of conditions the lemon tree is in (full sun?, how much water? fertilized? soil? etc).

And maybe a better description of the 'white substance' -- liquid, powder, sticky...?

There's a picture. (hopefully it worked). The white substance isn't liquid its more powder really.

Also,

The tree is in full sun and gets watered daily. It's been fine for years until the last few weeks.

The squiggly lines on the leaves are leaf miners. The damage is mostly cosmetic and either squish the larvae at the end of the trail or pick the leaf, heavy infestations can be harmful. https://www.ipm.ucdavis.edu/PMG/PESTNOTES/pn74137.html

The holes in the leaf is probably caused by a slug or snail. Put out bait for that. Also bait for ants. If you control ants you will have fewer problems with aphids and scale which are the bigger issues with citrus.

Leaf miners. I have the same problem with my Satsuma. I called my County Agent and he said not to worry. They will die off over winter. If they show up in the spring I am to call him again. Not a big concern at this time of year.
